rmaucher opened a new pull request #152: Add async IO API to NIO
URL: https://github.com/apache/tomcat/pull/152
It has very small perf improvements (except for "sendfile" situations) and non blocking frame read for HTTP/2. The performance looks rather similar to NIO2 as well, it is hard to find a very meaningful difference in my basic tests. The main downside is the two semaphores added.
This should allow actual use of the API by users (as long as they accept to give up on the APR connector), and also using it in Tomcat for HTTP/3 once NIO UDP is added.
Note: no doc, new "useAsyncIO" flag on the connector (default to false).
